Preheat the oven to 350 degrees. Combine the crumbs and the butter together. Mix well and press into a 10-inch springform pan. In a food processor, with the metal blade, mix the cream cheese until smooth. Add the sugar and blend. Add the eggs one at a time to thoroughly incorporate into the cheese mixture. Add the heavy cream. Add the flour, salt and vanilla and blend until smooth. In a steady stream, pour in the melted chocolate. Pour into the prepared pan. Bake for 1 hour and 15 minutes or until the cake is set. Remove from the oven and with a knife loosen the sides from the pan. This will prevent the cake from splitting down the center. Completely cool the cake before cutting. For the sauce: In a mixing bowl, combine all the ingredients together and allow to sit for 2-3 hours. Place a piece of the cake on the plate. Spoon the raspberries over the top. Garnish with whipped cream, chocolate curls, mint sprigs, powdered sugar, and cocoa powder.
